Avoid cold things, sour things. I also noticed whenever saliva came out from the side of mouth, it would hurt too, not just when I took the first bite. Like if someone was cooking up something delicious, and I was hungry, even the small walk to the dinner table, I could feel my jaw hurting a bit. So I lit candles in my room before dinner and I ran out to have dinner as soon as food was ready.
When I took first bite of every meal, I just let the first bite of food stay in my mouth without chewing at all until the soreness went away. I would repeat it a few times before it resumed normal. didn't take long. It didn't bother me much honestly.
Hope this helps.
